If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-03-20 17:30 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-03-07 16:30 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

The title of the presentation is "Exploring Satellite Telemetry with the CubeSat Simulator." Alan writes, "There are thousands of satellites in low earth orbit above us transmitting radio signals. Many of those signals contain telemetry, that is information about the spacecraft and its environment and built in sensors. "A great way to learn about satellite telemetry is to use the AMSAT CubeSat Simulator, a functional model of a 1U CubeSat designed for the classroom and public demonstrations. In this presentation, I'll show how to receive and interpret telemetry from it using the same tools and apps used for in orbit satellites launched by AMSAT and other amateur radio organizations. "I will also show you how you can build your own CubeSatSim with some intermediate soldering and 3D printing skills as the project is fully open sourced and available on GitHub." This one hour presentation is geared for those beginning to explore the world of satellite telemetry. The cost of the two day virtual event is $15. More information is available at https://www.qsotodayhamexpo.com/. [ANS thanks Alan Johnston, KU2Y, AMSAT VP Educational Relations for the above information.] --------------------------------------------------------------------- IARU Coordinates Two New Satellites The IARU has coordinated frequencies for the following two upcoming satellites: + PW-SAT3 PW-SAT3 is a 1U CubeSat mission to be flown by the Warsaw University of Technology. Students from the PW-Sat3 team are 1) designing a butane warm gas propulsion device that will be used to perform station-keeping maneuvers deorbiting maneuver; 2) AOCS system that will be used during propulsion maneuvers to align the satellite in the optimal orientation; 3) Earth Horizon Sensors made from industrial IR matrixes; 4) A camera module to capture views from space. The team also wants to implement a simple open transponder for radio amateurs to operate packet radio. They are also investigating the possibility to allow radio amateurs to download on-demand low-resolution images from the camera module. Proposing a UHF downlink using 2GFSK at 9k6 or 19k2. A downlink on 437.170 MHz has been coordinated. No launch date has been defined but deployment into a SSO 550km orbit is planned. More info from https://pw-sat.pl. + SAKURA Sakura is a 1U CubeSat mission sponsored by the Chiba Institute of Technology. APRS Mission Will provide APRS services including Digipeater functionality. SAKURA will carry two cameras, one to photograph sunspots and the other to photograph typhoons ,volcanoes and flooding areas. Amateur Radio stations should be able to receive a photograph in one pass. Proposing VHF and UHF downlinks using APRS and 4k8 AX25 GMSK respectively. Planning a launch to the ISS in January 2024 for deployment. Downlinks on 145.825 MHz and 437.375 MHz have been coordinated.

Annual reports are typical made available to the public up to a year or so after the financial records have been reviewed and approved by an external accounting firm. Although AMSAT has always published its financial statements and IRS filings every year, it now finds it useful to publish a corporate-like annual report to inform our stakeholders and prospective donors of our activities. Because the annual report is written for sometimes non-technical persons outside the traditional Amateur Radio world, experienced technical readers might find some passages over simplified descriptions of the engineering contributions and activities that AMSAT conducts. Nonetheless, AMSAT hopes that everyone can find the annual report a fairly descriptive picture of the work is does in helping to Keep Amateur Radio in Space.

[ANS thanks AMSAT for the above information.] --------------------------------------------------------------------- AMSAT Recognized for Educational Support [Editor's Note: This is an updated version of the story that appeared in ANS-071.] Instituto Universitario "Ignacio Da Riva" IDR and Escuela Técnica Superior de Ingeniería Aeronáutica y del Espacio of Universidad Politécnica de Madrid, Spain has recognized and thanked the members of AMSAT who have supported their educational endeavors by collecting telemetry data downloaded from the UPMSat-2 satellite around the globe. Mr. Rafael García Romero, EA4BPN, along with project director Dr. Elena Roibas, and IDR Director Dr. Angel Sanz Andres , on behalf of the UPMSat-2 team, penned the letter of recognition dated February 17, 2023 and recently received by AMSAT. The letter reads: "On the celebration of UPMSat-2 launch date anniversary of the second year in orbit, UPMSat-2 team would like to thank AMSAT for its support to the satellite downlink data gathering. The effort of AMSAT members is seen at IDR as a valuable 'citizen science' contribution to our project and is gratefully acknowledged. We expect that the UPMSat-2 will continue to work for another two years, therefore, it would bring an opportunity to continue with this fruitful collaboration. "With our best regards, we wish all the best for AMSAT members." UPMSat-2 sends 2-FSK data at 2400bps, with transmitted power of approximately 2.5 watts, on 437.405 MHz. Originally scheduled to launch in 1999, it was finally launched on September 3, 2020 from the Guiana Space Centre in Kourou, French Guiana. Launched on the flight VV16 of the Vega rocket, it entered a sun-synchronous orbit with an altitude of approximately 518 km."

[ANS thanks JoAnne Maenpaa, K9JKM for the above information.] + NASA is awarding more than $3.8 million to 21 museums, science centers, and other informal education institutions for projects designed to bring the excitement of space science to communities across the nation and broaden student participation in STEM (science, technology, engineering, and mathematics). Projects were selected for NASA’s Teams Engaging Affiliated Museums and Informal Institutions (TEAM II) program and TEAM II Community Anchor Awards. The selected projects will engage their communities in a wide variety of STEM topics, from aeronautics and Earth science to human space exploration. More information including a complete list of the organizations receiving funds is available at https://tinyurl.com/ANS-078-NASA-STEM. [ANS thanks SpaceRef.com for the above information.] + What time is it on the moon? A new era of lunar exploration is on the rise, with dozens of Moon missions planned for the coming decade. Europe is in the forefront here, contributing to building the Gateway lunar station and the Orion spacecraft – set to return humans to our natural satellite – as well as developing its large logistic lunar lander, known as Argonaut. As dozens of missions will be operating on and around the Moon and needing to communicate together and fix their positions independently from Earth, this new era will require its own time. Timing is a crucial element, adds ESA navigation system engineer Pietro Giordano: "During this meeting at ESTEC, we agreed on the importance and urgency of defining a common lunar reference time, which is internationally accepted and towards which all lunar systems and users may refer to. A joint international effort is now being launched towards achieving this.” More information at https://tinyurl.com/ANS-078-Lunar-Time. [ANS thanks the ESA for the above information.] + Looking for a fun project for that 3D printer sitting in your workshop? Look no further than Relativity Space in California for inspiration. Their Terran 1 will try to become the first 3D-printed, methane-fueled rocket to reach orbit. “There are a number of firsts here potentially on this rocket,” said Josh Brost, vice president of revenue operations at Relativity Space. “It has the chance of being the first liquid natural gas / liquid oxygen rocket to make it to orbit. It has, by far, the highest 3D-printed content of any rocket in history. We’re sitting at about 85% by mass, where I don’t think any other rocket has gone past maybe 4%.” Compared to a traditional rocket that has more than 100,000 parts, this 3D-printed rocket has less than 1,000 parts. After two aborted launches this month, Relativity Space is poised for another try on March 22. More information at https://spaceflightnow.com/2023/03/11/relativity-space-terran-1-glhf/.

Hi Alex, Yes I have noticed that I can often access the satellite with 5 watts when it is near the horizon where there is little or no activity. However when there are a number of active stations it becomes difficult to access with 50 Watts. I would think that you would have more success if you tried during unsociable hours:-) GL 73 Starr ZL3CU On 16/03/2023 7:37 pm, Fernando Ramirez via AMSAT-BB wrote: > Good evening Alex! > > The main issue during day passes is the overcrowding.

Good evening Alex! The main issue during day passes is the overcrowding. When it comes from the south you will notice that it is easy to get digipeated since a big part of the Continental US will be outside the footprint. Once the satellite enters higher latitudes you'll notice that is harder to get through. Once the footprint hits Europe and US is inside it, start praying but don't go crazy with the send button as it will make things worst. As for the delay I always recommend keeping it at 0 unless you have some kind of preamp that goes offline for several seconds. If the satellite doesn't pick you up it won't matter if you set it to 5, to 0 or to 1000. Best of luck from Nogales! 73 Fernando KF7R On Wed, Mar 15, 2023, 3:56 PM alex weimer via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > Thanks Sergei: I was worried maybe my antenna didn't have enough gain but > I hear the satellite very well.

Hi Alex, It’s common problem on GreenCube indeed because rx is overcrowded. Try different ReTX Delay. 5, for example. Because most of all set 0. Tonight I was roving to KO39 and it was quite impossible to break through wall also. Best 73 de ES4RM, Sergei Sent from my iPhone > On 16.

IO-117 question

I am having a peculiar problem when operating IO-117 (Greencube) When on an Ascending pass (South to Borth) I can hear the satellite very well but cannot access the digipeater! It makes no difference whether it is at 5 degrees or 50 degrees and whether the satellite is coming up from 180 or 030 degrees. I have no obstructions throughout these passes ! However when on a Descending pass (North to South) I can hear it as well as access the digipeater without any problems. I am running a IC9700 with a 14 element yagi horizontally polarized. I have 75 watts available and using the built in sound card from the IC9700 and the IO-117 modem and digi software from UZ7HO. Is there any reasonable explanation or is anyone else experiencing this problem? It has been frustrating to be able to see the DX stations and not be able to work them. Thanks for any help or suggestions on this matter. JACK KC7MG
